Tree Species Classification (CropModel)
Classifies tree crowns detected by DeepForest into 148 species using USDA PLANTS codes. Trained on RGB imagery from 29 NEON sites across North America.
Trained with NeonTreeClassification.
Usage
from deepforest import main
from deepforest.model import CropModel
detector = main.deepforest()
detector.load_model("weecology/deepforest-tree")
species_model = CropModel.load_model("weecology/cropmodel-tree-species")
results = detector.predict_tile(path="tile.tif", crop_model=species_model)
# results has columns: cropmodel_label, cropmodel_score
